Campaign spending in the dead-heat Connecticut governor's race continued at a feverish pace this week and has now gone past the $25 million mark.

Republican business executive Tom Foley reported that his campaign had spent $1.67 million in one week, including more than $1 million on television commercials and more than $500,000 on direct mail that is sent to voters' homes.

Foley's totals were listed in the final weekly filing to state officials before Tuesday's election against Gov. Dannel P. Malloy and petitioning candidate Joseph Visconti.

Malloy spent nearly $650,000 in one week from October 22 to October 28, including nearly $480,000 on television commercials. Visconti's cash-strapped campaign had raised $1,650 during the filing period and spent $1,534. As a result, Visconti had only $115 in cash on hand.

Malloy had about $450,000 on hand, while Foley had nearly $300,000 as Election Day quickly approaches.

With $6.5 million in public spending each, the candidates' totals essentially match the $13 million that has been raised by the two major SuperPACs that support each side in the dead-heat race. In addition, outside groups such as one run by former New York City Mayor Michael Bloomberg have poured money into the race. Bloomberg, who favors gun control, has spent $1.7 million on advertising on behalf of Malloy.

The Republican Governors Association contributed another $600,000 this week to Grow Connecticut, Inc., a SuperPAC that supports Foley and opposes Malloy. At $5.48 million, the RGA is the largest single contributor to the SuperPAC, which reported having $7.33 million overall, according to public filings. The group also has $1.5 million in outstanding expenses that have not yet been paid - and those are usually for television commercials that have been booked but not yet aired.

New Jersey Gov. Chris Christie, who chairs the RGA, is scheduled to return to Connecticut for the fifth time on Monday with a campaign stop in Windsor Locks - following previous visits to Greenwich, Stamford, Trumbulll, and Groton.

In the same way, a SuperPAC known as Connecticut Forward is supporting Malloy and bashing Foley, largely through television commercials. The national AFSCME union contributed $50,000 this week and the Democratic Governors Association gave another $330,000 - pushing the SuperPAC's overall fundraising total to $5.625 million.
